Description

Technical Field

[0001] The present invention belongs to the technical field of hookah devices, and particularly relates to an air-circuit hookah device. Background Art

[0002] Hookah appliances generate aerosols or smoke by heating eye ointment or lighting tobacco. These substances are filtered through liquid and finally inhaled by users through a smoke pipe.

[0003] Currently, hookah machines on the market usually use charcoal to directly heat the hookah paste or tobacco to generate aerosols or smoke. However, if the user smokes too fast, cold air will impact the hookah paste or tobacco, causing uneven heating of the hookah paste or tobacco and reducing the taste and quality of the smoke. In addition, the combustion of charcoal will produce harmful substances such as carbon monoxide. After passing through the liquid, these substances will still be inhaled by the user, posing a potential threat to the user's health. Summary of the Invention

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0028] It should be noted that if there are directional indications (such as up, down, left, right, front, back,...) involved in the embodiments of the present invention, the directional indications are only used to explain the relative positional relationship and movement conditions between components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0029] In addition, if the embodiments of the present invention involve descriptions such as "first", "second", etc., the descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include at least one such feature. In addition, if "and / or" or "and / or" appears throughout the text, its meaning includes three parallel scenarios. Taking "A and / or B" as an example, it includes scenario A, scenario B, or the scenario where both A and B are satisfied simultaneously. In addition, the technical solutions between various embodiments can be combined with each other, but it must be based on the ability of those of ordinary skill in the art to implement. When the combination of technical solutions results in contradictions or inability to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0030] In the prior art, hookah machines generally adopt a traditional heating method, that is, directly using charcoal to heat the tobacco paste or tobacco to generate the required aerosol or smoke. However, there are some problems with this heating method. When the user smokes at a relatively fast speed, cold air may directly impact the tobacco paste or tobacco, which will cause uneven heating during the heating process, thereby affecting the temperature and taste of the smoke. The smoke inhaled by the user may contain cold air that has not been fully heated, which will undoubtedly reduce the overall smoking experience and the quality of the smoke. Moreover, some harmful substances such as carbon monoxide are generated during the combustion of charcoal. Even if these harmful substances pass through the liquid filtration, they may still be inhaled by the user, thus posing a potential threat to the user's health.

[0031] Therefore, to solve the above problems, the present invention provides an air-circuit hookah device that adopts a new heating method, that is, using an electric heating component 2 to heat air and then using the hot air to impact and heat the tobacco paste 6.

[0032] Please refer to Figure 1 , this air-circuit hookah device includes an electric heating component 2 and a heat conductor 1. The electric heating component 2 includes a heating sheet 21, a main control board, and a battery. The heating sheet 21 is connected to the main control board through a wire, and the main control board is then connected to the battery. Under the control of the main control board, the heating sheet 21 generates heat to heat the heat conductor 1. The heat conductor 1 is preferably made of a metal material such as stainless steel or aluminum alloy, which has good heat conduction performance and can quickly transfer the heat of the heating sheet 21 to the air passing through its interior. A heating wire is provided inside the heating sheet 21, and this heating wire is connected to the main control board and has the function of automatically adjusting the temperature, making the heating uniform and safe.

[0033] Please refer to Figure 1 and Figure 2, a receiving cavity 11 and a gas guiding channel 12 are formed inside the heat conducting body 1. The receiving cavity 11 and the gas guiding channel 12 are in communication. The receiving cavity 11 is used to receive the capsule 5 containing the tobacco paste 6, and the gas guiding channel 12 is used to export the gas inside the receiving cavity 11. The heat conducting body 1 is also provided with a plurality of through holes 13, and the design of the through holes 13 enables the outside air to continuously enter the inside of the heat conducting body 1 and be heated. The shape and size of the heat conducting body 1 can be designed according to actual needs to ensure that it can effectively accommodate the capsule 5 and provide sufficient heating area.

[0034] During use, the user first installs the capsule 5 into the receiving cavity 11 of the heat conducting body 1. The capsule 5 contains the tobacco paste 6 inside. When the heating sheet 21 heats the heat conducting body 1, the air inside the heat conducting body 1 is heated to form hot air. The hot air enters the receiving cavity 11 through the through holes 13 on the heat conducting body 1 and impacts and heats the tobacco paste 6 in the capsule 5 ("impact heating" can be understood as: the heated hot air directly impacts the tobacco paste 6, causing the tobacco paste 6 to quickly heat up and generate aerosol or smoke). Since the temperature of the hot air is relatively high, it can quickly heat the tobacco paste 6 to the temperature at which smoke is generated, thus avoiding the problem of uneven heating caused by the direct impact of cold air on the tobacco paste 6.

[0035] In addition, the air circuit hookah device further includes components such as a liquid storage tank 3 and a smoking pipe 4. The liquid storage tank 3 is used to hold liquids such as clean water or fruit juice to filter harmful substances in the gas introduced through the gas guiding channel 12. The smoking pipe 4 is connected to the liquid storage tank 3 and is used to draw out the smoke filtered by the liquid for the user to inhale. Among them, the air flow direction is indicated by arrows in Figure 1 It is shown by arrows.

[0036] In summary, the air-circuit hookah device provided by the embodiment of the present invention includes a heat conductor 1, an electric heating component 2, a liquid storage tank 3, and a smoking pipe 4. The heat conductor 1 is formed with a receiving cavity 11 and a gas guiding channel 12 communicating with the receiving cavity 11. The receiving cavity 11 is used to receive a capsule 5. The heating sheet 21 of the electric heating component 2 is attached to the outer peripheral wall of the heat conductor 1 to heat the heat conductor 1. The liquid storage tank 3 is arranged below the receiving cavity 11. The liquid storage tank 3 is used to hold a liquid to filter the gas introduced through the gas guiding channel 12. The smoking pipe 4 is connected to the liquid storage tank 3 to lead out the gas filtered by the liquid in the liquid storage tank 3. Wherein, the heat conductor 1 is provided with a plurality of through holes 13. The through holes 13 are used to introduce external air, so that after the air is heated by the heat conductor 1, it enters the receiving cavity 11 to impact the tobacco paste 6 in the heating capsule 5. In the embodiment of the present invention, by arranging a plurality of through holes 13 in the heat conductor 1 and attaching the heating sheet 21 to the outer peripheral wall of the heat conductor 1, the air in the through holes 13 of the heat conductor 1 is heated by the heating body. Since the through holes 13 communicate with both the external air and the receiving cavity 11, the cold air of the external air can continuously enter the through holes 13 and be heated, and the heated hot air can continuously enter the receiving cavity 11 to impact the eye ointment in the heating capsule 5. The heated tobacco paste generates aerosol or smoke and is discharged through the gas guiding channel 12. The gas guiding channel 12 is connected to the liquid storage tank 3, so that after the aerosol or smoke is filtered by the liquid in the liquid storage tank 3, it is sucked by the user through the smoking pipe 4.

[0037] In the embodiment of the present invention, the air is heated by the electric heating component 2 and then the hot air is used to impact and heat the tobacco paste 6. Compared with directly heating the capsule 5 with charcoal fire, the embodiment of the present invention can prevent harmful substances such as carbon monoxide generated by the burning of charcoal fire from being inhaled by the user, thus ensuring the health of the user. In addition, since the electric heating component 2 is used to heat the air, the user can more precisely control the heating temperature to obtain a better smoking experience. At the same time, the impact heating method of the hot air on the tobacco paste 6 can also ensure that the tobacco paste 6 is evenly heated, avoiding the problem of uneven heating caused by the direct impact of cold air on the tobacco paste 6.

[0038] In some embodiments, please refer to Figure 1 and Figure 2 , in order to facilitate placing the capsule 5 into the receiving cavity 11, the top 55 of the receiving cavity 11 is designed to be open. Therefore, a cover 7 needs to be equipped to close the top 55 of the receiving cavity 11.

[0039] Please refer to Figure 1 and Figure 2, the heat conductor 1 includes a heat conducting portion 14 and a connecting portion 15, and the connecting portion 15 is connected to the bottom end of the heat conducting portion 14. A receiving cavity 11 is formed within the heat conducting portion 14, and an air guiding channel 12 is formed within the connecting portion 15. The heat conducting portion 14 can be made of a highly heat conductive material, such as copper or aluminum alloy, to ensure that heat is quickly transferred to the gas within the through hole 13. The connecting portion 15 is designed to be slender in shape to better guide the air flow through the air guiding channel 12. The top end of the receiving cavity 11 is open so that the tobacco paste 6 can be placed into the receiving cavity 11 from the top end of the receiving cavity 11. The top end of the receiving cavity 11 can be understood as the upper end of the receiving cavity 11 in the normal use state of this hookah device. After the tobacco paste 6 is placed into the receiving cavity 11, the cover body 7 of this air circuit hookah device is closed on the top end of the receiving cavity 11, thereby closing the top end of the receiving cavity 11.

[0040] It can be understood that the more times the air flow bends along the traveling path, the greater the resistance it encounters and the slower the flow speed. Therefore, the through hole 13 extends from the bottom end to the top end of the heat conducting portion 14 (i.e., the through hole 13 penetrates through the heat conducting portion 14), allowing cold air to enter the through hole 13 from the bottom end of the through hole 13, flow out from the top end of the through hole 13 and enter the top end of the receiving cavity 11, and finally enter the air guiding channel 12 from the bottom 57 of the receiving cavity 11, thereby forming a tortuous traveling path. Among them, the through hole 13 extends from the bottom end of the heat conducting portion 14 to the top end of the heat conducting portion 14, that is, the through hole 13 penetrates through the top and bottom ends of the heat conducting portion 14. Specifically, the through hole 13 can penetrate through the heat conducting portion 14 along a straight line direction (as Figure 1 shown), or can penetrate through the heat conducting portion 14 along a curved direction (such as a spiral direction).

[0041] Please refer to Figure 1 and Figure 2 , since the top end of the heat conducting portion 14 is penetrated by the through hole 13, when the cover body 7 is closed on the top end of the heat conducting portion 14, it should be avoided that the cover body 7 blocks the top end of the through hole 13. Therefore, in the embodiment of the present invention, the cover body 7 only closes on the first edge 141a of the top end of the heat conducting portion 14 so that the top end of the through hole 13 is completely exposed. And a diversion space 71 is formed between the cover body 7 and the top end of the heat conducting portion 14, and the diversion space 71, the through hole 13 and the receiving cavity 11 are all connected, so that the gas within the through hole 13 can enter the receiving cavity 11 after passing through the diversion space 71. Therefore, the cover body 7 not only plays a sealing role, but also forms a diversion space 71 with the top end of the heat conducting portion 14 for air circulation.

[0042] In an embodiment of the present invention, by adding a cover body 7, and the heat conductor 1 includes a heat conducting portion 14 and a connecting portion 15, a receiving cavity 11 is formed within the heat conducting portion 14; the connecting portion 15 connects to the bottom end of the heat conducting portion 14, and an air guiding channel 12 is formed within the connecting portion 15; wherein, a heating sheet 21 is attached to the outer peripheral wall of the heat conducting portion 14; a through hole 13 extends from the bottom end to the top end of the heat conducting portion 14; the top end of the receiving cavity 11 is open, and the cover body 7 covers the first edge 141a at the top end of the heat conducting portion 14 to form a diversion space 71; the diversion space 71, the through hole 13, and the receiving cavity 11 are all in communication. Thus, when a user uses this air circuit hookah device, outside air enters the through hole 13 from the bottom end of the through hole 13 and becomes hot under the heating action of the heat conductor 1; the heated air flows out from the top end of the through hole 13, crosses the diversion space 71, and enters the receiving cavity 11. Since there is eye ointment in the receiving cavity 11, the hot air can impact and heat the tobacco paste 6. In this way, the flow path of the air flow forms a bent shape, and this bent shape surrounds the heat conducting portion 14, so that the gas can be fully heated.

[0043] In some embodiments, please refer to Figure 1 and Figure 2 , in order to achieve a sealed connection between the cover body 7 and the first edge 141a and reduce gas leakage, corresponding settings are made to the first edge 141a. Specifically, the heat conducting portion 14 has a first surface 141A connecting to the top end of the through hole 13; the first edge 141a is formed by upward extension of an annular portion of the first surface 141A and surrounds a plurality of through holes 13, so that the through holes 13 can be exposed in the area surrounded by the first edge 141a. Thus, gas can enter the area surrounded by the first edge 141a through the first through hole 13113, forming a smooth air flow.

[0044] Please refer to Figure 1 and Figure 2 , the first edge 141a is snap-connected to the edge of the cover body 7. Further, the cover body 7 can be made of a deformable plastic material, so that when the first edge 141a and the cover body 7 are in mutual contact, the deformation of the cover body 7 can reduce the gap between the cover body 7 and the first edge 141a to achieve sealing.

[0045] In the embodiment of the present invention, through the extended setting of the first edge 141a, it not only facilitates the tight connection between the first edge 141a and the cover body 7, but also enables the air flow to smoothly enter the receiving cavity 11 through the area surrounded by the first edge 141a. Therefore, the setting of the first edge 141a not only realizes a sealed connection, but also enables the air flow to flow smoothly.

[0046] In some embodiments, please refer to Figure 1 and Figure 2, in order to enable the heated gas to quickly enter the capsule 5, the first surface 141A is designed accordingly. Specifically, the first surface 141A includes a first conical surface A1 and a first plane A2 connected to the outer edge line of the first conical surface A1. The first conical surface A1 faces the diversion space 71; at least one of the first through hole 131 and the second through hole 132 penetrates the first conical surface A1. In this way, the design of the first conical surface A1 gradually changes the flow direction of the gas, smoothly guiding it from the diversion space 71 to the accommodation cavity 11. Since the first conical surface A1 has a gradually shrinking shape, the gas will be guided when flowing through the first conical surface A1, and the flow rate increases, which is conducive to the gas quickly entering the capsule 5.

[0047] Therefore, the setting of the first conical surface A1 in the embodiment of the present invention improves the efficiency of the gas entering the capsule 5 in the accommodation cavity 11.

[0048] In some embodiments, please refer to Figure 2 , in order to enhance the air flow in the through hole 13 to absorb more heat, the number of through holes 13 is increased in the cross-section of the heat conduction part 14 (the cross-section is perpendicular to the extension direction of the through hole 13). Specifically, the through hole 13 includes at least two groups of holes arranged staggeredly, namely the first through hole 131 and the second through hole 132, which are arranged along the circumferential direction of the accommodation cavity 11. The circumferential direction of the accommodation cavity 11 is indicated by a dotted arrow Z in Figure 2 .

[0049] Through the staggered arrangement of the first through hole 131 and the second through hole 132 in the embodiment of the present invention, not only the ventilation volume per unit cross-section in the heat conduction part 14 is increased, but also the contact area between the air in the through hole 13 and the heat conduction part 14 is increased, enabling the heat of each part of the heat conduction part 14 to be quickly transferred to the air in the through hole 13, improving the heat conduction efficiency.

[0050] In some embodiments, in order to ensure that there is always a gap between the capsule 5 and the inner wall of the accommodation cavity 11, the top 55 of the accommodation cavity 11 is designed with a mounting part 111. After the capsule 5 is mounted on the mounting part 111, a first gap 114 is formed between the side wall 112 of the accommodation cavity 11 and the capsule 5, and a second gap 115 is formed between the bottom wall 113 of the accommodation cavity 11 and the capsule 5. In addition, the top 55 of the accommodation cavity 11 and the first gap 114 are both communicated with the inside of the capsule 5.

[0051] In the embodiment of the present invention, please refer to Figure 2 and Figure 3, an installation part 111 is provided at the top end of the accommodation cavity 11, ensuring that there is always a certain gap between the capsule 5 and the inner wall of the accommodation cavity 11. Therefore, when the aerosol or smoke generated after the tobacco paste 6 in the capsule 5 is heated, it can successively pass through the first gap 114 and the second gap 115 and finally enter the air guiding channel 12. It can be understood that since the first gap 114 is adjacent to the heat conducting part 14, the aerosol or smoke will still be heated when passing through this gap, making its taste more intense.

[0052] In some embodiments, please refer to Figure 2 and Figure 3 , the installation part 111 is an annular step surface surrounding the inner side of the accommodation cavity 11. The top end of the capsule 5 has a radially protruding annular lapping part, and this annular lapping part is pressed against the annular step surface, making the annular step surface and the annular lapping part fit together, so that the gas can only enter the capsule 5 after passing through the through hole 13. In other words, the setting of the annular step surface and the annular lapping part makes the gas entering the capsule 5 all heated gas, thus avoiding the user from inhaling cold air.

[0053] In some embodiments, the capsule 5 of the air circuit hookah device is designed to be replaceable. This means that when the user needs to use the device, they only need to place a new capsule 5 in the accommodation cavity 11 (please refer to Figure 1 ). Therefore, the capsule 5 is usually stored separately to ensure better preservation of the tobacco paste 6 inside. To maintain the airtightness of the capsule 5, the capsule 5 is sealed until it is used.

[0054] Specifically, please refer to Figure 4 and Figure 5 , the capsule 5 is filled with tobacco paste 6 inside; the top 55 of the capsule 5 is provided with a first tear-off part 51. After this part is torn off, a first air vent 52 will be formed, which is used to introduce the gas in the diversion space 71 into the inside of the capsule 5; the side of the capsule 5 is provided with a second tear-off part 53. After tearing off, a second air vent 54 is formed, and this hole is used to guide the gas in the capsule 5 to the first gap 114.

[0055] Through the setting of the tear-off part of the capsule 5 in the embodiment of the present invention, the capsule 5 can be better preserved.

[0056] It can be understood that for the tobacco paste 6 at the bottom 57 of the capsule 5, hot air needs to travel to the bottom 57 of the capsule 5 to impact and heat the tobacco paste 6. During this process, the heat of the hot air will be somewhat dissipated, making it difficult for the tobacco paste 6 at the bottom 57 of the capsule 5 to be fully heated, thus affecting the taste.

[0057] In some embodiments, please refer to Figure 6 and Figure 7In order to ensure that the tobacco paste 6 at the bottom 57 of the capsule 5 can be fully heated, the air circuit tobacco water device is also equipped with a positioning member 81 and a pushing member 82. One end of the positioning member 81 is connected to the inner wall of the cover 7, and the other end is used to abut against the top 55 of the capsule 5, so that the top 55 of the capsule 5 is fixed. The pushing member 82 is arranged on the bottom wall 113 (such as Figure 3 The pusher 82 abuts against the bottom 57 of the capsule 5, so that the bottom 57 of the capsule 5 can gradually move upward relative to the side 56 of the capsule 5 as the tobacco paste 6 in the capsule 5 gradually decreases. The pusher 82 can be a cylinder or other components that can push the bottom 57 of the capsule 5 upward.

[0058] It is understood that the positioning member 81 and the pushing member 82 will not prevent the gas flow in the air circuit hookah device. For example, the positioning member 81 is a plurality of needle-like structures or columnar structures, as long as it does not prevent the gas flow.

[0059] In this way, when there is little tobacco paste 6 in the capsule 5, the pushing member 82 pushes the bottom 57 of the capsule 5 upward, thereby reducing the distance between the tobacco paste 6 and the first air hole 52, and the hot air coming in from the first air hole 52 can quickly contact the tobacco paste 6, thereby reducing the heat loss of the hot air before heating the tobacco paste 6.

[0060] In some embodiments, please refer to Figure 6 and Figure 7 The pusher 82 is a spring. The bottom 57 of the capsule 5 is provided with a deformation portion 58, which is fixedly connected between the bottom 57 of the capsule 5 and the side 56 of the capsule 5. The hardness of the side 56 of the capsule 5 and the bottom 57 of the capsule 5 is higher than that of the deformation portion 58.

[0061] Specifically, the deformation part 58 is made of soft natural silica gel. The deformation part 58 can be formed into one piece with the bottom 57 of the capsule 5 and the side 56 of the capsule 5 by injection molding or other molding processes. In this way, when the bottom 57 of the capsule 5 moves upward, no air leakage occurs between the bottom 57 and the side 56 of the capsule 5.

[0062] Since the pusher 82 is a spring, when the amount of tobacco paste 6 in the capsule 5 is large, the pressure of the capsule 5 on the spring is large, and the deformation of the spring is large; when the amount of tobacco paste 6 in the capsule 5 is small, the pressure of the capsule 5 on the spring is small, and the deformation of the spring is small. At this time, the bottom 57 of the capsule 5 moves upward, and the tobacco paste 6 moves upward. The distance between the tobacco paste 6 and the top 55 of the capsule 5 is small, so the hot air can quickly impact the tobacco paste 6, and the heat of the hot air is not easy to dissipate, so that the tobacco paste 6 is fully heated, and the aerosol or smoke is more concentrated.

[0063] It should be noted that the top 55, side 56, and bottom 57 of the capsule 5 are the corresponding parts in the orientation of the capsule 5 in its normal use state.

[0064] In some embodiments, referring to Figure 1 , to reduce heat loss, the air-circuit hookah device further includes a heat insulation cotton 9 and a housing 10. The heat insulation cotton 9 is attached to the outside of the heating sheet 21 to reduce the heat dissipation of the heating sheet 21.

[0065] The housing 10 at least surrounds the heat insulation cotton 9, and of course, it can also surround the water tank 3, etc. It can be understood that the battery, main circuit board, etc. of the electric heating component 2 should also be arranged inside the housing 10. The housing 10 should be spaced apart from the heat insulation cotton 9 to reduce heat loss caused by the heat transfer of the housing 10; it can be understood that the setting of the housing 10 reduces the air circulation outside the heat insulation cotton 9, thereby reducing the heat dissipation of the heating sheet 21 and the heat conduction part 14. The inside of the housing 10 is communicated with the outside air so that the outside space can enter the inside of the housing 10.

[0066] The above are only exemplary embodiments of the present invention, and do not limit the patent scope of the present invention accordingly. Any equivalent structural transformation made under the technical concept of the present invention by using the content of the specification and drawings of the present invention, or directly / indirectly applied in other related technical fields, is included in the patent protection scope of the present invention.
